Okay, so the new Buck 80 insert is up and running. This is my first modern wood burner. I had an old, and I mean old, smoke dragon in my workshop that I only used from time to time and 2 open firepalces in the house. The insert was installed by the dealer on Friday 01/18 but the first burn was not until Saturday because the Buck folks forgot to include a cat probe with the stove. I’m hoping this is not a sign of things to come! And wouldn’t you know it Saturday was near record heat with temps reaching near the 60° mark. No matter, I fired it up and opened all the windows and doors. Temps in the house approached the 80° mark in no time flat. Temps outside have steadily dropped since Saturday’s high, with last night reaching a low of 5°. Temps in the house remained fairly constant at 72° to 74°. From 6am Monday until about 11:40pm Monday I only burned 6 pieces of 2 year old ash. At 11:40 the fire box had a nice bed of coals on which I placed 3 splits of 2 year old black locust for the overnight burn. At 6am this morning I still had big, chunky locus coals brightly glowing in the fire box and the house was 72° and the cat temp was 800°. So far this is what I’ve noted about the 80: It is fairly easy to reach a dangerously high cat temp with very little wood and all the air controllers closed. I wouldn’t have thought is possible to reach suck high temps so quickly and with so little air. I’ve twice had to open the bypass damper and crank the fan to it’s max to keep the cat from reaching the “too hot” mark on the probe. This worries me because I don’t know what is happening to the cat during the overnight burn. The instructions that I downloaded from Buck and that came with the insert are very definite about loading the stove “from front to back” (n – s) yet in order to use wood of the maximum recommended length of 22” it has to be loaded side to side (e – w). I’m not sure what this means other than I may be forced to shorten a whole bunch of split and seasoned firewood in order to get the proper burn. This monster makes a lot of heat! I am burning it most of the time with all the air controls fully closed and cat temps at about 1100°to 1300°. Does this sound correct? Is having so little air going to damage anything? This morning I added 2 pieces of ash to the coals and the cat temp dropped to about 500° which is in the “inactive” range according to the cat probe. I opened the air controls, including the shotgun air, to their wide open position. And because the cat probe was reading in the “inactive” range, I opened the bypass damper until the cat temp cam up to just over 600°. Was this correct? How do I know when the cat is working; that is what changes do I look for in the fire box? Or are there no visible changes? Any other tips and tricks you kids may have for more efficient and safe operation would be greatly appreciated by this newbie!
